8 speaker coffee shop

Hey, my family is opening up a coffee shop with 8 ceiling speakers. I am trying to find an inexpensive reciever to power all 8 speakers in some sort of stereo setup. For example running 6 speakers on stereo and using a zone 2 for the last 2. Overall high end fidelity is not really important, just that sound is coming out of the speakers...know what i mean.

I have done some research, but the problem i am running into is that on all of the recievers i have looked at it turns the main zone to 5.1, to turn on stereo in zone 2. Only 7 speakers.

Maybe a used stereo amp would solve this on some models? However that is a little confusing for me, and this needs to be done right.

Thanks so much in advance

A stereo receiver would do fine, just get a four zone speaker selector with impedence matching and connect all four pairs to it. If you get a 100 W receiver it will divide the power to each pair to 25W but that should be plenty for background music.

Steve, for low volume background music you don't even have to go that fancy. You just need a decent, solid (probably used) stereo receiver with A and B speaker outputs. Can you access the wiring to the speakers? If so, you just hook them up as 4 pairs, each wired in series. By wiring pairs in series, you double the impedance. Then you hook each pair to the A and B of each channel. Most receivers are wired so running both pairs hooks them up in parallel, which halves the impedance and you end up with the actual impedance of the speakers and don't risk overheating the amp.

If you need specific instructions on how to do all this, just let me know. It wouldn't be a good way to set up something you want to play loud, but for this use it should be just what you need.

Re: 8 speaker coffee shop

I just got back from the shop today and the installer has already done that....just wired them into i think 4 or 2 pairs. So i just need a decent stereo reciever? I think i have a 20+ year old pioneer stereo laying around somewhere? Or do i need something modern?

Last time i checked ebay normal stereo recievers were not all that pricey.

Would this one work?

Onkyo TX-8522 100 Watt Stereo Home Theater Receiver - eBay (item 220196041986 end time Feb-01-08 19:44:39 PST)

Thanks for all the responses!!

Update...I ordered that reciever this afternoon, we'll see how it works out.
